Well, what do you expect when every Tom Dick and Harry can make a coin for as less as $5 (using waves), host a website with less than $10 (any basic shared cloud hosting) and market it in social media and platforms like this.
Anything which they get is nearly profit.
Yeah they can get easy returns on investment like that like it is nothing, even if only twenty people buy, they will still be in profit. That is why there are many ICO's right now, so be careful of them because I think some just have a rip off idea from another altcoin, just edited. Some have a kind of unique idea but in a way that crypto world does not really necessarily needs it. There are a few who might not be scam though but still beware most is scam.
